Harold E. Palmer,
The Principles of Language-Study
“ New methods often bewilder those who have become used to the old ones; unfamiliar grammatical systems are bewildering to those who think that one system of grammar is common to all the languages of the world. It is disconcerting to face the fact that languages have classical and colloquial grammars existing side by side, which grammars are mutually exclusive in many respects; it is more especially bewildering to those who have never made any study of colloquial language. ”
